... Odd that you use so much heat, I was having problems with the toner not transfering to the board so used ore heat, it got better, I then 'uprated' the...
Jam5411's recent EUREKA moment with using the Simple Green wipes on a inkjet printed pcb got me to thinking. There has been a lot of discussion on the best...
Yes, the thing is, this is easy to over-do. If you apply too much, say propylenglycol, you'll get ink running all over the place. BTW diluted ink (from a...
Sigh.... You missed the point again, Steffie. Once you have identified a property, and have a tool to measure the effects, the tool can be used to optimize the...

Andrew, I would think that the minimum purchase of one $200+ roll (40 ft by 12") puts the technology out of the range of most hobbyists. There is a big ...
... No - sorry. Don't know where to buy smaller ammounts. There will be cheaper places than think-tink but thats the smallest size I imagine. I would have...
Hi guys, About a year ago or so there was some talk of using EDM for isolation milling and such. Stefan was tinkering a bit with it and another fellow did some...
I was curious about the stuff sold for removing ferric chloride stains, so I looked up the Mega Electronics data sheet on the stuff they sell (its made by...
